Seamless Design. Superior Strength. Smarter Roofing by PHOENIXX.

PUF Sandwich Roof Panels

A PUF sandwich roof panel is an insulated roofing system made by injecting rigid Polyurethane Foam (PUF) between two pre-painted metal sheets. This creates a strong composite panel that combines lightweight construction with superior insulation and load-bearing capacity. PUF roof panels are widely used where temperature control, energy efficiency, and long service life are critical. Unlike conventional roofing sheets, PHOENIXX panels are engineered to achieve a load-bearing capacity far greater than the combined strength of individual layers. This allows panels to safely bridge wide spans while remaining lightweight. PHOENIXX PUF sandwich roof panels are specially designed to perform reliably in Indian weather conditions, including high ambient temperatures, heavy rainfall and humidity, strong winds (up to 120 km/h), industrial pollution and UV exposure. This makes them ideal for projects across all regions of India.

Frequently Asked Questions

Everything you need to know about PUF Sandwich Roof Panels

What is a PUF sandwich roof panel?+
A PUF sandwich roof panel is an insulated roofing system made by injecting rigid Polyurethane Foam (PUF) between two pre-painted metal sheets. This creates a strong composite panel that combines lightweight construction with superior insulation and load-bearing capacity.
What is the life span of a PUF sandwich roof panel?+
PHOENIXX PUF sandwich roof panels typically last 25-30 years or more with proper installation and maintenance. PVDF-coated panels can last even longer with superior UV resistance.
Are PUF roof panels suitable for cold storage buildings?+
Yes, PUF roof panels are ideal for cold storage due to their excellent thermal insulation properties. The low thermal conductivity (0.024-0.030 W/mK) maintains consistent temperatures and reduces energy consumption.
Do PUF roofing panels require additional insulation?+
No, PUF sandwich roof panels are pre-insulated roofing systems. The rigid polyurethane foam core provides built-in thermal insulation, eliminating the need for secondary insulation.
Are PHOENIXX panels customizable?+
Yes, PHOENIXX panels are fully customizable. Thickness (30-120mm), length (up to 20m), colors (RAL standard), and coatings (SMP/SDP/PVDF) can all be specified based on project requirements.
How do PUF panels compare with metal roofing sheets?+
PUF sandwich panels provide built-in insulation, better energy efficiency, noise reduction, and longer service life compared to plain metal roofing sheets. They also reduce HVAC costs significantly.
What is the difference between PUF and PIR roof panels?+
PUF panels offer excellent insulation at economical cost, ideal for warehouses and factories. PIR panels provide enhanced fire resistance and are recommended for pharma, cold storage, and high-compliance projects.
What factors affect PUF roof panel price?+
The cost depends on panel thickness, foam type (PUF or PIR), steel thickness, paint coating (SMP/SDP/PVDF), quantity, and project location. PHOENIXX offers competitive pricing with custom manufacturing flexibility.
How fast can PUF sandwich roof panels be installed?+
PUF sandwich roof panels can be installed 40-60% faster than traditional roofing systems due to large effective cover width (1000mm), interlocking panel design, and no requirement for secondary insulation.
What slope is required for PUF roofing?+
A minimum roof slope of 5-7 degrees is recommended for proper water drainage. Higher slopes improve drainage and reduce the risk of water ponding.
Can PUF roofing panels withstand Indian weather conditions?+
Yes, PHOENIXX panels are specifically designed for Indian conditions including high ambient temperatures, heavy rainfall, humidity, strong winds (up to 120 km/h), industrial pollution, and UV exposure.
Are PHOENIXX PUF panels environmentally friendly?+
Yes, PHOENIXX PUF roof panels are CFC & HFC free, energy-efficient, and designed to reduce carbon footprint. They support green building initiatives and sustainable construction practices.
Can solar panels be installed on PUF roofing?+
Yes, solar panels can be installed using non-penetrating mounting systems or with proper flashing and sealing for through-fixings. The structural strength of PUF panels supports solar installations.
What is the manufacturing process for PUF roof panels?+
Pre-treated steel/aluminum sheets are roll-formed into roofing profiles, rigid PUF is injected between sheets, foam expands and cures bonding permanently to metal skins, panels are cut to size, coatings applied, and quality checked before dispatch.
Why choose PHOENIXX over other PUF panel manufacturers?+
PHOENIXX offers engineering optimized for Indian conditions, faster delivery timelines, custom panel sizes up to 20 meters, competitive pricing, and dedicated technical and after-sales support.
